BACKGROUND OF THE INVENTION

The present invention relates generally to toothbrushes, and, moreparticularly, to a toothbrush which may have an oral care dispenser,such as a breath freshening, teeth cleaning gel capsule, and an oralcare accessory, such as a toothpick.

The advantages of good dental hygiene are well known. Often, however,toothbrushes are forgotten when one is traveling or away from home.Hotels, health care facilities, nursing homes, hospitals, daycarefacilities, schools, airlines, etc. have a need for single usedisposable or limited multiple use toothbrushes that may be economicallysupplied to and discarded by individuals without a toothbrush and/or awater supply. Such toothbrushes could be used in vending machines, ordistributed in large quantities for simple, portable use from anywhere.

Various types of disposable, limited use, or portable toothbrushes areknown in the art. For example, some toothbrush systems have attempted tomeet some of these needs by providing toothpaste within the toothbrushitself, through an integrated channel, for distribution through thetoothbrush and around the bristles. This approach can be less economicaldue to the added manufacturing costs of toothbrushes with integratedchannels. In addition, the toothpaste in some of these integratedchannel toothbrushes, not being properly sealed, has a tendency tobecome dry, hard and stale.

Thus, there is a need in the art for a waterless, toothbrush having atoothpick connected thereto to enable cleaning in between teeth or otheraccessory, and a dispenser containing a dentifrice or other oral carematerial and being connected in the bristle or cleaning element portionof the toothbrush for dispensing the dentifrice to the teeth to provideteeth cleaning and breath freshening or other oral care benefits.

SUMMARY OF THE INVENTION

The present invention solves the problems of the related art byproviding in one embodiment a waterless toothbrush having a toothpickconnected thereto to enable cleaning in between teeth, and a rupturabledispenser containing a dentifrice and being connected in the bristleportion of the toothbrush for dispensing the dentifrice to the teeth toprovide teeth cleaning and breath freshening, all of which deliver acleaning, polishing, whitening, between teeth cleaning, and breathfreshening action in addition to enhancing the cleaning efficiency of atypical disposable or limited use toothbrush. The toothbrush of thepresent invention in this embodiment combines three benefits into onetoothbrush: (1) tooth surface cleaning provided by the toothbrushbristles or other cleaning elements and the dentifrice in the rupturabledispenser; (2) between teeth cleaning provided by the toothpick; and (3)breath freshening provided by the dentifrice in the rupturabledispenser.

As embodied and broadly described herein, the present invention isbroadly drawn to an oral care toothbrush, preferably comprising: ahandle having an oral care head mounted to one end of the handle with anoral care accessory mounted to an opposite end of the handle. Aplurality of oral care elements such as cleaning/massage elements, whichcould be bristles, extend outwardly from the outer surface of the head.The head also includes structure for dispensing oral care material inthe oral care field of the head.

In a preferred practice of the invention the oral care toothbrush ischaracterized by its small size and light weight so that it is readilyadaptable for travel use. The oral care toothbrush is preferably capableof having multiple functions by including an accessory as part of thetoothbrush such as a toothpick, dental floss or tongue cleaner.

In one practice of this invention the oral care toothbrush includes atoothpick formed at one end of the handle; and a head connected atanother end of said handle, said head having a bristle block thatincludes a plurality of bristles and retains a gel capsule therein, thegel capsule containing a mouth care solution. In further embodiments,the gel capsule can be replaced by a quantity of toothpowder, toothpasteor a tooth cleaning gel dentifrice, to provide the cleaning benefits ofthe dentifrice within the rupturable dispenser.

Further scope of applicability of the present invention will becomeapparent from the detailed description given hereinafter. However, itshould be understood that the detailed description and specificexamples, while indicating preferred embodiments of the invention, aregiven by way of illustration only, since various changes andmodifications within the spirit and scope of the invention will becomeapparent to those skilled in the art from this detailed description. Itis to be understood that both the foregoing general description and thefollowing detailed description are exemplary and explanatory only andare not restrictive of the invention, as claimed.

Among the advantages of various practices of the invention are that thesize and configuration of the toothbrush allows discreet hygienic use,such as no fingers in the mouth, adapting it to be readily used inpublic areas.

DETAILED DESCRIPTION OF THE INVENTION

The following detailed description of the invention refers to theaccompanying drawings. The same reference numbers in different figuresidentify the same or similar elements. Also, the following detaileddescription does not limit the invention. Instead, the scope of theinvention is defined by the appended claims and equivalents thereof.

FIGS. 1-4 illustrate one practice of the present invention wherein anoral care toothbrush 10 includes a head 12 and a handle 14. Head 12 maybe a refill head and thus be removably connected to handle 14, or head12 may be permanently connected to head 12 within the practice of thepresent invention.

The majority of handle 14 and a portion of head 12 may be molded from avariety of rigid materials, including plastics, resins, etc., such as,for example, polypropylene. An end portion of handle 14, opposite theend head 12 is attached to an accessory, preferably a toothpick 16formed of a resilient and soft thermoplastic elastomer. Toothpick 16 maybe a refill and thus be removably connected to handle 14, or toothpick16 may be permanently connected to handle 14 within the practice of thepresent invention. Toothpick 16 provides a mechanism for spot cleaningbetween teeth. Forming toothpick 16 of a soft elastomer provides morecomfortable interproximal cleaning between teeth. Toothpick 16 could,however, be made of a stiff rigid material similar to the main portionof handle 14, or could simply be a rubber or elastomeric pick adhered orotherwise mounted to the end of handle 14.

Portions 18 of handle 14 may also be formed of a resilient and softthermoplastic elastomer. The thermoplastic elastomer which formstoothpick 16 and handle portions 18 may be a thermoplastic vulcanate(TPV) consisting of a mixture of polypropylene and EPDM (ethylenepropylene diene monomers) which is available as SANTOPRENE (brand),described in U.S. Pat. No. 5,393,796, or VYRAM (brand), another TPVconsisting of a mixture of polypropylene and natural rubber. BothSANTOPRENE and VYRAM (brands) are elastomers marketed by AdvancedElastomer Systems. Other suitable elastomers include KRATON, a brand ofstyrene block copolymer (SBC) marketed by Shell, and DYNAFLEX G 2706(brand), a thermoplastic elastomer marketed by GLS Corporation and whichis made with KRATON (brand) polymer.

Handle 14 may further include dimples, bumps, or ridges protruding fromportions of its surface, and providing a decorative appearance to handle14 and enhanced gripping of handle 14 during use of toothbrush 10. Thedimples may be formed from the same material as soft elastomer portions18 of handle 14 or from the same material as the majority of handle 14(e.g., a rigid material such as polypropylene). All or part of handle 14could be made of any suitable material, such as plastic, wood, metal orvarious natural materials which are biodegradable.

Preferably handle 14 is made of a generally flat or oval shape ratherthan cylindrical in its gripping portion which would be between thespaced elastomer portions 18, 18 to facilitate the gripping of thehandle.

As shown in FIG. 4 another portion of head 12, defining a bristle orcleaning element block 22 of head 12, may also be formed of a resilientand soft thermoplastic elastomer, such as the thermoplastic elastomerused to form handle portions 18. Cleaning block 22 may include one ormore depressions 24 provided in a surface 30 thereof with an opening 30therein that provides a cushioning effect to a rupturable dispenser,preferably a gel capsule 32, contained therein, as described more fullybelow. Cleaning block 22 further includes a multitude of cleaningelements which could be conventional filament, preferably nylon, orelastomeric bristles or fingers 26 extending integrally outwardly fromthe outer surface of head 12. In the illustrated embodiment as bestshown in FIG. 4, all of the cleaning elements 26 extend outwardly fromthe outer surface of block 22 the same distance so as to create agenerally flat surface. Alternatively, however, some elements 26 may beshorter or longer than other elements 26.

The term “cleaning elements” as used herein is intended to be used in ageneric sense as cleaning elements or massage elements arranged in acircular cross-section shape or any type of desired shape, includingstraight portions or sinusoidal portions. It is to be understood thatthe specific illustration of the cleaning elements is merely forexemplary purposes. The invention can, however, be practiced withvarious combinations of the same or different configurations (such asstapled, in-mold tufting (IMT) bristle technology as disclosed in U.S.Pat. Nos. 5,609,890, 5,390,984, and 5,533,791, the disclosures of whichbeing incorporated by reference herein in their entirety, etc.) and/orwith the same or different bristle materials (such as nylon bristles,spiral bristles, rubber bristles, etc.). Similarly, while FIGS. 1-4illustrate the cleaning elements 26 to be generally perpendicular to theouter surface of head 12, some or all of the cleaning elements 26 may beangled at various angles with respect to the outer surface of head 12.It is thereby possible to select the combination of configurations,materials and orientations to achieve specific intended results, such asenhanced cleaning, tooth polishing, breath freshening, tooth whiteningand/or massaging of the gums.

As stated above, the cleaning block 22 may include one or moredepressions 24 which are designed to receive and retain an oral caredispenser, such as a rupturable gel capsule 32 therein. The one or moredepressions 24 can be varied in size so as to accommodate not onlyvarying size dispensers 32, but varying quantities of toothpowder, atoothpaste or tooth cleaning gel dentifrice or other oral care material,for delivery to the dentiture as the elements 26 extending from theblock 22 are applied thereto, during use of the present invention suchthat the oral care material enhances the cleaning of the dentiture bythe cleaning elements. While the present invention can be manufacturedcontaining a packed toothpowder, toothpaste or tooth cleaning geldentifrice and used repeatedly by the user refilling the dispenser withtoothpowder, toothpaste or tooth cleaning gel dentifrice, it ispreferably used with one or more gel capsules 32 contained therein. Mostpreferably the present invention is used with a single gel capsule 32,supplied therewith, so as to be most easily transported, used, andsubsequently disposed of; however, it may also be used repeatedly withreplaceable gel capsules 32, and then disposed of.

It is preferred that the depression is in the form of a cushioned socket28 sized and shaped to receive and retain the gel capsule 32, withoutpremature rupture of the gel capsule 32 prior to use thereof duringapplication of the bristle block 22 to the dentiture and brushingthereof. Cushioning socket 28 opening 30, and the material making upbristle block 22 provide a cushioning effect for gel capsule 32 toprevent gel capsule 32 from rupturing prior to use.

Gel capsule 32 holds and applies a mouth care solution onto bristles 26of toothbrush head 12. The mouth care solution may be a toothpaste, agel, a mouthwash, or similar dentifrice or oral hygiene product, or acombination of the same contained in the rupturable capsule 32.Preferably gel capsule 32 is a liquid-filled gel capsule havingfrangible, thin walls that easily rupture or burst when rubbed againstthe teeth, or dissolve when mixed with the saliva of a user. Thematerials making up gel capsule 32 and the oral or mouth care solutioncontained therein preferably are consumable by the user of toothbrush10, eliminating the need for water, a sink, or a waste receptacle toexpectorate the gel capsule 32 or its contents. The mouth care solutionremains in gel capsule 32 until toothbrush 10 is ready for use.Preferably, gel capsule 32 is fully sealed, helping the mouth caresolution to remain fresh until use.

In use, gel capsule 32 would be pressed against the teeth and burst orrupture or dissolve, applying the mouth care solution over cleaningelements 26. The user then may brush their teeth with toothbrush 10. Theuser may also use toothpick 16 to clean between teeth, either before orafter brushing. After the user has used toothbrush 10, one may, but notnecessarily, then easily and economically dispose of toothbrush 10.

In one preferred aspect of the present invention, the entire structureof toothbrush 10, including head 12, handle 14, and toothpick 16, ismolded as one integral structure, using a conventional two-componentinjection molding operation typically used in the manufacture oftoothbrushes. This enables toothbrush 10 to be economically and quicklymanufactured. Although toothbrush 10 may have a variety of sizes anddimensions, it is preferred that toothbrush 10 have a small profile,with head 12 being small enough to cover one tooth at a time and handlebeing thinner than conventional, everyday toothbrush handles. Toothbrush10 is thus readily portable or space saving.

The toothbrush 10 of the present invention provides many benefits,including the cosmetic benefits of brushing one's teeth in a form thatcan be used when one is away from home, and away from a water supply.The cosmetic benefits achieved by the toothbrush 10 of the presentinvention include the cleaning of debris between teeth with toothpick16, broad tooth surface cleaning (particularly the front teeth) withcleaning elements 26 and the mouth care solution of gel capsule 32, andbreath freshening with the mouth care solution of gel capsule 32.

In addition to the cosmetic benefits, the toothbrush 10 of the presentinvention also provides economic benefits in the form of an inexpensivetoothbrush that is both quickly and economically manufactured.Toothbrush 10 also provides a mechanism for maintaining oral health,without the need for toothpaste, water, mouth wash, and containers tohold the same. Thus, toothbrush 10 is also very convenient to use.

Although FIGS. 1-4 illustrate a manually-operated, disposabletoothbrush, the present invention may also be practiced where the headincludes one or more power or electrically operated movable sectionscarrying cleaning elements. Such movable section may oscillate in arotational manner or may oscillate linearly in a longitudinal directionwith respect to the longitudinal axis of the head or may oscillatelinearly in a lateral or transverse direction with respect to thelongitudinal axis of the head. The movable section may oscillate in andout in a direction toward and away from the outer surface of the head.The movable section may rock back and forth with respect to the outersurface of the head. The movable section may rotate continuously in thesame direction, rather than oscillate. Any suitable drive mechanism maybe used for imparting the desired motion to the movable section. Whereplural movable sections are used, all of the movable sections may havethe same type and direction of movement, or combinations of differentmovements may be used.

In accordance with one aspect of this invention the cleaning elementsmay be in the form of bristles made from conventional materials, such asnylon, as well as from a combination of materials so as to provide theproper stiffness in an economical manner. For example, the cleaningelements could be made of a flexible resilient material, such as TPE anda lesser expensive material such as LLDPE (linear low densitypolyethylene) or EVA (ethylene vinyl acetate) or a TPE. The cleaningelements could be made of a blend of TPE and either LLDPE, EVA, orpolypropylene. Preferably, the two materials are combined to provide astiffness of less than 600 MPa. The blend of materials would give theproperties of conventional nylon bristles, while offering reduced costs.For example, there would be lower manufacturing costs by injectionmolding instead of conventional bristle tufting. Alternatively theresilient material could be a single material, such as hard TPE (i.e.Shore A 80 hardness), straight LLDPE or straight EVA.

The cleaning elements may be of any desired shape. For example, thecleaning elements could be of cylindrical shape having a uniformdiameter throughout their length. Alternatively, the cleaning elementscould taper from the root of each cleaning element where it extends fromhead 22 to its outer cleaning end. Since a preferred practice of theinvention is to provide a small lightweight toothbrush the dimensions ofthe various components of toothbrush 10 are preferably small. Thus, forexample, each cleaning elements may extend outwardly from the outersurface of cleaning block 12 a distance no greater than 10 mm andpreferably no greater than 8 mm and most preferably no greater than 6mm. Where tapered cleaning elements are used the root diameter should beno greater than 1.5 mm, preferably no greater than 1 mm, most preferablyno greater than 0.7 mm or no greater than 0.5 mm or no greater than 03.mm. The diameter could then decrease in size to no greater than 0.2 mmat a distance of no greater than 6 mm from the base of the cleaningelement. The taper relationship of diameter at a distance location abovethe root diameter could be a range of no greater than 1 mm at a distanceof no greater than 10 mm, preferably no greater than 0.6 mm at adistance of no greater than 8 mm, most preferably no greater than 0.2 mmat a distance of no greater than 6 mm. Preferably, the length of theentire toothbrush 10 is no greater than 5 inches, preferably no greaterthan 4 inches, and more preferably no greater than 3.75 or 3 or 2.50inches, and may be in the range of 2 to 4 inches.

As illustrated in FIGS. 1 and 4 the cleaning elements define a cleaningfield in the head and the dispenser 32 is mounted within this cleaningfield. The cleaning elements 26 preferably extend outwardly from thecleaning block 22 to be approximately flush with the outer surface ofthe gel bead or capsule 32, as shown in FIG. 4. The invention, however,can also be practiced where the cleaning elements extend either agreater distance or a lesser distance than the dispenser 32. Sincetoothbrush 10 is intended to be both small and lightweight, it ispreferred that toothbrush 10 weigh no more than 3 grams. The small sizeis such that it can be held completely within the palm of an adult user.Head 12 is of a size that it would correspond to the size of anindividual tooth or an individual tooth and the interproximal areas.Head 12 could be made of any suitable shape and is preferably ofcircular or oval shape having a maximum lateral dimension or diameter ofno greater than 13 mm, preferably no greater than 12 mm and mostpreferably no greater than 11 mm. Where head 12 is of non-circular shapeits maximum lateral dimension is 14 mm.

As shown in FIG. 2 head 12 is preferably at an angle between 0 degreesand 90 degrees to the longitudinal axis of handle 14. The preferredangle is from 20 degrees to 70 degrees and more preferably from 30degrees to 60 degrees. The cleaning elements could be perpendicular tothe outer surface of head 12 or could also be at an angle to the outersurface such as in the range of 60 degrees to 90 degrees or in the rangeof 75 degrees to 90 degrees.

In one practice of the invention the cleaning elements could be hollow,such as hollow bristles, which are capable of absorbing a medicament bycapillary action. Such practice of the invention would be particularlyuseful for children where a medicament or some form of flavor could bedispensed from the hollow cleaning elements. It is also possible toleach antibacterial material from the cleaning elements. In one practiceof the invention where the cleaning elements are used to dispense oralcare materials the cleaning elements themselves may be considered as theoral care dispensers without requiring additional dispensers such ascapsule 32.

Where specific parameters and characteristics have been given forcleaning elements, the invention could be practiced where other cleaningelements do not include those parameters and characteristics.

FIGS. 5-6 show other variations in the practice of this inventionwherein the cleaning elements are in the form of a single mass having anirregular outer surface. As shown in FIG. 5 the mass 34 is similar tothat of “steel wool” as used in household cleaning or could be part ofVELCRO formations, such as hooks or loops.

FIG. 6 shows a variation where the cleaning element 36 is of a singlemass of foam for cotton which could be used as a swab for oral carematerial. The outer surface of the swab could be generally planar orcould have surface irregularities. In such practice of the invention thecleaning element 36 could be impregnated with the oral care material orcould be dipped into oral care material so as to absorb the material andthereby the cleaning element 36 would also function as the oral caredispenser. Such swab type cleaning elements are gentle for children,particularly infants.

The invention could be practiced where the various components of thetoothbrush 10 are segmented for manufacturing and assembly purposes.Such segmented components could also be detachably connected together soas to permit the interchangeability of the components thereby providingthe possibility for the substitution of different components in thecombination. Thus, the head 12 could be detachably connected to thehandle 14. FIG. 7, for example, illustrates head 12 to be detachablymounted to handle 14 by a snap fitting 38 which may be of any suitableconstruction as is known to those of ordinary skill in the art.

The concept of a detachable interconnection may also be used wherein thedispenser 32 is detachably mounted in the head 12 or wherein the oralcare accessory, such as toothpick 16, is detachably mounted to handle14. Thus, as later described with respect to FIGS. 12 and 13 thetoothbrush and its various components could be packaged wherein the samepackage includes a plurality of toothbrushes and/or a plurality ofdifferent components such as heads, dispensers or accessories.

FIG. 8 shows a further practice of the invention wherein a piezoelectriccrystal 40 is provided in the handle 14 at the junction with head 12 soas to cause the head 12 to vibrate during use. Alternatively the head 12could be mounted to a rotatable shaft extending from the handle andhaving an eccentric weight on the shaft to cause the head to vibrate.

Although FIGS. 1-3 illustrate an oral care accessory 16 in the form of atoothpick, other types of accessories 42 could be used as schematicallyshown in FIG. 9. As illustrated therein such accessory 42 would bemounted to the end of handle 14 similar to the mounting of toothpick 16.Such mounting could be detachable or of a permanent nature. Examples ofsuch oral care accessories include tongue cleaners, floss holders or aninterproximal brush. Similarly, the accessory could be of a swab or foamtype similar to the cleaning element 36 of FIG. 6 or could be of thesingle mass of roughened material such as the cleaning element 34 ofFIG. 5.

FIG. 10 shows another variation of the invention wherein the toothbrushis particularly adapted for use by children. Such use is enhanced byproviding any suitable ornament or caricature 44 on the toothbrush, suchas on the handle or on any other suitable location including thebackside of the head. Such ornament 44 could be detachably mounted sothat it could be kept by the child after the rest of the toothbrush isthrown away. Other aspects of the invention which make it desirable foruse by children include the possibilities of dispensing various types oforal care materials including materials having special flavors, toothnumbing materials, anti-sensitive materials or various medicaments.

The toothbrush could also be made of various colors for different partsof the toothbrush. For example, soft elastomer 18 could be made of adifferent, such as a contrasting, color with respect to the remainder ofhandle 14 which would be made of a rigid material. Similarly, the head12 could be made of a different color than the rigid portion of thehandle and/or the soft elastomer portions 18. The cleaning elements 26could be made of distinct colors and the dispenser 32 could also be madeof a distinct color. Along the same lines the accessory such astoothpick 16 or other accessory 42 could be made of a distinct color.These various colors could be contrasting or complementary with eachother. Thus, for example, the various colors could differ only slightlyin color or shade.

FIG. 11 illustrates another practice of the invention wherein the handle14 has a hollow chamber 46 in which the oral care material could becontained. Chamber 46 leads to a passageway 48 which extends to the head12 such as terminating in a plurality of branches 49 at the outersurface of head 12 within the cleaning field. In order to dispense theoral care material located in the chamber or reservoir 46 handle 14would have sufficient resiliency so that it can be squeezed therebyforcing the material from the handle to the head into a dispensingcavity or one or more dispensing openings.

Any suitable oral care products could be dispensed from the dispenser.Such products include, but are not limited to the gel capsule 32 aspreviously described and could contain toothpaste, tooth powder or couldbe a small vial of mouthwash having a gel, a powder or a liquid. Such avial could be separately included in a package containing thetoothbrush. The materials could be flavored and could be provided insets of different flavors and/or different characteristics such asmedicaments, numbing materials, etc.

Where the dispensers 32 are in the form of beads, different beads orcapsules could be used with different colors/flavors to enhance consumerappeal. As described the capsule 32 could be an impregnated bead thatburst. Suitable beads include those supplied by Mane Inc.

Any suitable methods may be used for forming toothbrush 10 and itsvarious components. For example, multi-component injection molding couldbe used to integrally couple various components such as the cleaningelements and the head and/or the handle. This could be done in anautomated or multiple step process. The handle could be rotocast blowmolded to form a hollow squeeze handle that would be usable in theembodiment shown in FIG. 11.

FIGS. 12-13 show different manners of packaging toothbrushes inaccordance with this invention. As shown in FIG. 12, for example, asingle package 50 could contain a plurality of toothbrushes 10 all ofwhich could be the same or could differ from each other. The package 50could be of any conventional construction, such as a blister pack, whichmight include a hole 52 to permit the package to be hung for displaypurposes.

FIG. 13 illustrates a variation wherein the package 54 includes one ormore toothbrushes 10 and a plurality of other components 56 which couldbe accessories or dispensers or other components. The components couldinclude a small vial of mouthwash. Preferably, the package 50 or 54would be hermetically sealed to assure freshness. Such hermetic sealingis particularly desired to prevent moisture from reaching gel capsule 32and causing the capsule to burst.

As is apparent the present invention provides an oral care toothbrushwhich is preferably small in size and portable and can be convenientlyused away from home under circumstances, such as travel, where water isnot readily available.

The invention could be practiced with a combination of variouscomponents which do not involve “toothbrush” usage. In that sense theinvention is an oral care device or the like, rather than strictly beinga toothbrush. Where used as a toothbrush or the like, the invention mayhave the advantages, because of the size and configuration, to allowdiscreet hygienic use, such as no fingers in the mouth, adapting it tobe readily used in public areas.
